A fi ti fil d February 10, 1903. Serial No. 142,73et.

To 1] whom 7 may concern:

Be it known that we, Amos Ronnnuow VVIL- son and LESTER MARTIN DULL, citizens of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Apparatus for Mannfacturing Glassware, of which the following is a specilication.

The present invention relates particularly to machines of that character wherein the. articles are pressed, though there are certain features that are capable of use with other types of machines, as will be apparent to those skilled in the art.

The object is to provide a machine which will manufacture glass articles with great rapidity and is automatic in its operation to such an extent that the services of skilled workmen are not required.

One of the features of this invention relates to a machine including in its make-up molds, cores, means for feeding glass to the molds, and mechanism for introducing the cores into the molds prior to the feeding of glass thereto. This arrangement is of great importance, as it insures not only the proper positioning of the cores, but also the complete filling of the molds without previously measuring the batch to be placed therein, as has been necessary heretofore so far as we are aware.

Another feature resides in the mechanism for operating the cores, said mechanism being simple and positively operated. by the means which drives the machine.

A still further feature relates to simple means for receiving the articles from the molds and delivering them from the machine.

An embodiment of the invention is illustrated in the accompanying drawings, though it is to be understood that the invention is not limited to the specific details of construction shown and described, but is open to various changes and modifications within the scope of the claims hereto appended.

in the drawings, Figure l is a top plan view of the machine. Fig. 2 is an elevation of the same. Fig. 3 is a longitudinal sectional view. Fig. at is an elevation of a diil'erent side of the machine from that illustrated in Fig. 3. Fig. 5 is a horizontal sectional View. lfig. 6

is a detail section illustrating the mechanism for operating the cores. Fig. 7 is a detail sectional view through one of the molds after it has been filled, and Fig. 8 is a vertical sectional view through the receiveucup.

Similar reference-numerals indicate corresponding parts in all the figures of the drawings.

Illn the embodiment herewith illustrated suitable glass-feeding mechanism is employed, which is illustrated in Figs. 1 and i. This mechanism per we fully described and claimed in a copending application Serial No. l i2,733, to which attention is invited for a complete understanding of the structure. As is shown, however, a melting-tank 10 is employed, from which projects a reservoir 11, the projecting end thereof being surroumled by aheating-chamber 12. The top 13 of this reservoir extends beyond the same and constitutes the top of the heating-chamber. It also forms a platform 14; through and to the upper face of which extends a glass-conduit 15, that leads from the lowerfront end of the reservoir 11. The chamber 12 and the conduit are heated by a suitable burner 16. An air-pipe 17 is connected with the reservoir and is arranged to conduct air under pressure to the same. Thus it will be seen that when air is admitted to the reservoir the glass will be forced through the conduit 15 to the platform 1 1. The machine hereinafter described coactswith this glass-feeding mechanism and is constructed substantially as follows:

A base 18 of suitable dimensions is provided and from the same projects a standard 19, made rigid at its lower end by suitable braces 20, extending to the base. Upon this standard is journaled a carrier, comprising a hub 21, carrying radial arms 22, connected by webs 23. On the outer ends of the arms 22 are secured molds 2 1, comprising sections 25, hinged together, as shown at 26. The molds are provided with cavities 27, that are of the shape of the articles to be manufactured, a portion of these cavities beinglocated in each section. .ln the present instance the machine is intended for making insulators; but it will be readily seen that articles of various kinds can be manufactured by changing the shapes of the cavities. The molds are movable over the platform i l and they are provided in their bottoms with inlet-channels 28, arranged to aline with the discharge end of the glassconduit 15.

The upper end of the standard 19 carries a casting that is located above the carrier, and i one part of this casting is in the form of a bracket 29, that overhangs the base and is provided with a vertical journal-bearing 30. i One of the lower braces is extended, and at i the end thereof is located an upright journal box 31 alined with the bearing 30. In these bearings is rotatably mounted a driving-shaft 32, operated by any suitable power and carl l rying on its lower portion a gear-wheel 33, meshing with an idler 34, that is attached to another idler 35. This idler 35 is in gear with a large wheel 36, secured to the hub of the carrier. As a result it will be seen that i the carrier is slowly and continuously rotated from the driving-shaft. The molds are auto- 1 matically opened and closed, and to this end a i cam 37 is arranged between the gear-wheel i 36 and the radial arms 22, being held against rotation by any suitable means, in the presl ent instance said means being illustrated in i the form of stirrups 38, secured to the cam i and to the lower end of the standard. The cam 37' is provided at the desired place with i an inset portion 39, which is preferably 10- I cated a short distance from the glass-feeding mechanism, as indicated in Fig. 5. One section of each mold is rigidly secured in any 1 suitable manner to one of the arms 22, the 1 other section being capable of swinging toward and from the fixed section. This movl able section carries a rearwardly-prejectingl and trailing finger 40, having at its free end a roller 41, which bears against the periphery ofthe cam. During the greater part of i the movements of the molds the sections are held in closed positions by the coaction of the fingers and the cam; but when the fingers reach the inset portion 39 the sections can be i swung apart by any well-known means as, r for instance, a spring 39, interposed therebetween as fully illustrated in Fig. 5. Extending over the molds and constituting a part of the carrier are radial arms 42, the outer ends of which have eyes 43, in which l are screwed. the shanks 44 of cores 45, that are i provided with tapering screw-faces, as shown. i The pitch of the threads of the shanks must be the same as those of the cores; but it will be understood that under certain conditions plain-faced cores may be employed. The i cores are thus movable out of and into the l molds and are provided with caps 46, which I are arranged to cover the open upper ends of I the cavities of said molds. The upper ends of the shanks are provided with clutch nienibers 47, comprising plates having upstanding l pins 48. The means for moving these cores out of and into the molds will now be de- I scribed. I The casting hereinbefore mentioned as being located at the upper end of the standard besides having the bracket 29 is also provided l with an oppositely-extending bracket49, hav- I The l ing a cross-beam at its outer end.

brackets 29 and 49 are provided with horizontally-disposed bearings 51, in which is journaled a counter-shaft 52, connected at one end by bevel-gears 53 with the driving-shaft 32. The other end carries a bevel-gear 54, meslr ing with a similar gear 55 on a stub-shaft 56, journaled in bearings 57, that constitutea part of the cross-beam 50. The ends of the crossbeam 50 are provided with upright collars 58, in which are journaled sleeves 59, having at their upper ends bevel gear-wheels 60, that mesh with similar wheels 61 on the ends of the stub-shaft 56. Slidably mounted in the sleeves 59 are vertically-moving rods 62, that are keyed, as shown at 63, so as to revolve with the sleeves, these rods thus being rotated in opposite directions. Their lower ends are provided with clutch members 64, comprising plates having depending pins 65, that are arranged to engage with the pins 48 of the clutch members of the cores. Because of the gearing employed it will be evident that the rods 62 and the clutch members carried thereby will be rotated at a comparatively high rate of speed. The rods 62 are suspended from swinging arms 63, and for this purpose the outer ends of said arms are provided With sockets 64, in which are slidably mounted shanks 65, the free ends of which are bifurcated, as shown at 66, and are fastened to collars 67, through which the rods pass and in which they are freely rotatable. Other collars 68 are fastened to the rods 62 on opposite sides of the collars 67, and thus said rods are secured to the arms 63, though they are free to rotate. These arms 63 really constitute parts of bell-crank levers journaled upon the bracket 49, the other arms 69 of these levers being arranged in depending relation on opposite sides of the counter-shaft 52. The

. arms 69 are provided at their free ends with offset pins '10, that bear against cams Tl, fastened to the counter-shaft and clearly illustrated in Figs. 2, 3, an l 6. By this arrangement itwill be seen that the suspended rods are continuously rotated and at predetermined intervals they are lowered, thus bringing their clutch members into engagement with the clutch members of the cores that are located beneath the same. As a result one of the cores will be raised while the other will be lowered, the one that is raised being located just in advance of the place where the molds open, and the one that is lowered in like manner being located just in advance of the glass-feeding mechanism, as set forth in Fig. 5.

In the present embodiment the following novel means is employed for receiving and removing the molded articles. A guideway 72 is secured to the base of the machine directly beneath the place where the molds open and extends some distance outside of the same, and in this guideway is mounted a reciprocatory slide (3, in which 1s ournaled an upstanding stem 74, carrying a receiver quired.

This receiver is m the v 75 at its upper end. form of a cup and comprises a metallic shell 76, having a socket 77 in its lower end that receives the upper end of the stem 7 i. It is lined with a non-combustible cushion substance 78, such as asbestos or similar material. The cup is movable to and away from a position beneath the opening-mold upon a reciprocation of the slide, and this slide is reciprocated by the following means: A countershaft 79 is journaled in suitable bearings 80 upon the base, one end of the shaft receiving power from the main driving-shaft 32 through oblique-toothed gears 81. The other end of this shaft carries a cam 82, provided with a groove 83. The slide has a finger 84, that is offset, as shown in Fig. i, and is provided with a pin 85,engaging in the cam-groove. The receiver is also rotated, and for this purpose a stationary rack 86 is fastened to the guideway at one side of the same, and a pinion 87 attached to the stem 74 meshes with the rack.

it will of course be understood that the various elements-such as gears, cams, &c. are of the necessary sizes and shapes and are so related that the different operations will be performed in proper order. These operations are substantially as follows: As an empty mold comes into position upon the platform 14 and over the discharge end of the conduit 15 air under pressure is admitted to the reservoir. This causes molten glass to be elevated through the conduit into the mold which is therefore filled, a suitable vent being allowed at the upper end for the escape of the air. As the mold moves away from its position the supply of compressed air is cut off until the next mold is in place. The filled mold travels two-thirds of the distance about the machine, and thus the glass will cool to an extent sufficient to hold its shape. At this point the clutch member 65 is suddenly lowered into engagement with the clutch member of the core and two rotating together said core will be elevated out of the mold. As this operation is comparatively rapid, the rotation of the carrier will not interfere with it. After the core has been raised the mold begins to open, and this opening movement is completed at the time that the receiving-cup is located beneath the same. The article therefore drops into said cup, which is automatically projected and at the same time rotated, so that the article is carried away from the machine and its shapeis better preserved by the rotation. From the receiver the said article is taken by hand. After passing the discharging means the mold will close, and just before it again reaches the glass-feeding mechanism the core is again lovered to its proper posit-ion within the same. It will therefore be seen that articles of various kinds may be rapidly manufactured by means of this machine and that the services of skilled workmen are not re- Ill an i it is especially desired to call attention to the following features: First, the feeding of the glass to the mold after the core has been placed therein. As before stated, this avoids the necessity of 'u'edetermined meas ured batches that have heretofore been necessary and the forcing of the cores into the same. The means for actuating the cores both in lowering and raising the same is very simple and is driven by the same power employed in operating the machine as a whole. The device for removing the molded articles is also an important feature of the present invention, as it prevents breakage and prevents to a large extent misshapen articles should the glass not be hardened to a sufficient extent as the article drops from the mold.

From the foregoing it is thought that the construct-ion, operation, and many advantages of the liBlQln-QlQSClllM-Btl invention will be apparent to those skilled in the art without fur ther description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
